First Claim
1. An ambient information notification apparatus for a vehicle comprising:
- an interior sound acquisition device that acquires a sound in a compartment of the vehicle, which is referred as an interior sound;
an ambient information presentation sound generator that generates an ambient information presentation sound, which satisfies a first condition and a second condition with regard to the interior sound; and
an ambient information presentation sound output device that outputs the ambient information presentation sound,wherein the first condition is that a sound pressure level of the ambient information presentation sound is higher than the interior sound in a predetermined frequency band, and is lower than or equal to the interior sound in other frequency band, andwherein the second condition is that the ambient information presentation sound is provided by stereophony, in which a sound image localization direction approximately directs to a virtual sound source.
